Famous quotes containing the words ball and/or mill:

    “Eating’s going to be a whole new ball game. I may even have to buy a new pair of trousers.”
    —Lester Piggott (b. 1935)

    “—First a shiver, and then a thrill,
    Then something decidedly like a spill,—
    And the parson was sitting up on a rock,
    At half-past nine by the meet’n’-house clock,—
    Just the hour of the Earthquake shock!
    MWhat do you think the parson found,
    When he got up and stared around?
    The poor old chaise in a heap or mound,
    As if it had been to the mill and ground!”
    —Oliver Wendell Holmes, Sr. (1809–1894)
